# of CELLSMOST ARE UNICELLULAR = ONE CELL
But some are multicellular!
Let’s see. You’re young, outgoing, single celled…
NOURISHMENTNot all protists are alike!
•Some are ANIMAL-LIKE PROTISTS. Heterotrophs that have to EAT food.
•Some are PLANT-LIKE PROTISTS: Autotrophs that can MAKE THEIR OWN FOOD.
•Some are FUNGUS-LIKE PROTISTS: Heterotrophs that DECOMPOSE MATERIALS.
LOCOMOTIONMost CAN move!
They all have a different way…EXAMPLES:•Paramecium: use cilia
• Made of microtubules
• Move by wave-motion
•Amoeba use pseudopods
• Move by extending
•Euglena use flagella
• Made of microtubules
• Move by wave motion
Passive Transport:
•Use spores
•Move by wind
HELPFUL Ex.• •Digest cellulose in termite
guts• •Algae & Phytoplankton are
a huge part of aquatic ecosystems!
• •Algae is used in nori, ice cream, salad dressing, pudding, candy bars, pancake syrups, eggnog, plastics, waxes, transistors, deodorants, paints, lubricants, and artificial wood.
• •Fungus-like protists play huge roles as decomposers in our ecosystem.
HARMFUL Ex.• –Plasmodium = Malaria• –Trypanosoma = African Sleeping
Sickness• –Entamoeba = Dysentery• -Giardia• –Water Mold = Potato Blight
Potato Blight
Trypanosoma
